The SELCTV database : the susceptibility of arthropod natural enemies to agricultural pests to pesticides

Creator:: Theiling, Karen M.
Abstract:: Documentation of the side effects of pesticides on arthropod natural enemies has expanded rapidly since the 1950's as part of an increase in non-target side effects literature. Most reviews have been based on empirical analysis of selected literature. The SELCTV database was developed to make a larger information base accessible...

Monitoring pesticide resistance in Psylla pyricola Foerster from western Oregon pear orchards

Creator:: Follett, Peter A.
Abstract:: A modified slide-dip bioassay was used to survey and establish baseline resistance levels in Psylla pyricola Foerster from western Oregon orchards to four pesticides. Orchards selected in the Hood River, Rogue River and Willamette Valleys spanned a wide range of environmental and management conditions. During the study period of 1982-1983,...

Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...

Effects of early season immigration on acaricide resistance of Tetranychus urticae Koch on strawberry in the California Pajaro and Salinas valleys

Creator:: Miller, Richard W. (Richard William), 1958-
Abstract:: In the Pajaro Valley near Watsonville, California, twospotted spider mite (Tetranychus urticae Koch) populations were surveyed in 1983 and '84 to detect the influence of immigrants from nursery plants or surrounding vegetation on subsequent resistance development to cyhexatin and formetanate in strawberry fields. Susceptible mites (cyhexatin LC50 = 0.0039 %...

Chemotherapeutic and nontarget side-effects of benomyl to the orange tortrix (Argyrotaenia citrana) and the braconid endoparasite Apanteles aristotelia

Creator:: Sewall, David K.
Abstract:: Benomyl, a systemic benzimidazole fungicide was incorporated into artificial diet and evaluated for its oral toxicity to nonparasitized and parasitized third instar orange tortrix larvae, Argyrotaeniae citrana (Fernald) and its food chain toxicity via the host to the solitary braconid endoparasite Apanteles aristoteliae Vierek. Concentrations of benomyl ≤ 300 ppm...

On admissibility among affine sets of linear estimators

Creator:: Pereira, Clifford Brian
Abstract:: We describe a general finite-dimensional inner product space setting for studying the characterization of admissible linear estimators. We extend the results of LaMotte (1982) and derive necessary and sufficient conditions for an estimator to be admissible among an arbitrary affine set of linear estimators when they are compared using quadratic...

Ion-pair high pressure liquid chromatography techniques for the determination of quaternary ammonium compounds

Creator:: Starbuck, Brian J.
Abstract:: Quaternary Ammonium Compounds, Qams, are an important class of chemicals which present interesting challenges to analysts. This thesis reports results of investigations on uses of ion-pairing techniques for separations and detection of Qams. Special apparatus for post-column solvent extraction of liquid chromatographic eluates was developed as part of this work....

The influence of map complexity on interpolation accuracy.pdf

Creator:: Young, Brian K.
Abstract:: In this paper "map complexity" refers to the inherent intricacy of a mapped geographic pattern. Map complexity and sample size are two variables shown to influence the accuracy of interpolated dasymetric maps. An automated experiment was designed to investigate the precise relationship among map complexity, sample size, and the accuracy...
